How to clear a function?

How to clear a function?

I'm using a basic slideshow plugin but my problem is need to have a multiple slideshow. 
This is the sample code:
$('a.lightbox').bind('click', function(){
var aIDL = $(this).attr('href');
$(aIDL + ' ' +'.detail_list').bjqs({
animtype  : 'slide',
width     : 458,
automatic : false
            }); 

}); 
every time i click a a tag it will execute the function. the problem is if the user need to click multiple times. so i want to clear the function after the user click a close tag.
